In the simplest terms, what we are doing in Korea is this: We are trying to prevent a third world war.

I think most people in this country recognized that fact last June. And they warmly supported the decision of the Government to help the Republic of Korea against the Communist aggressors. Now, many persons, even some who applauded our decision to defend Korea, have forgotten the basic reason for our action.

It is right for us to be in Korea. It was right last June. It is right today.

I want to remind you why this is true.

The Communists in the Kremlin are engaged in a monstrous conspiracy to stamp out freedom all over the world. If they were to succeed, the United States would be numbered among their principal victims. It must be clear to everyone that the United States cannot and will not sit idly by and await foreign conquest. The only question is: When is the best time to meet the threat and how?

The best time to meet the threat is in the beginning. It is easier to put out a fire in the beginning when it is small than after it has become a roaring blaze.

And the best way to meet the threat of aggression is for the peace-loving nations to act together. If they don’t act together, they are likely to be picked off, one by one.

If they had followed the right policies in the 1930’s if the free countries had acted together, to crush the aggression of the dictators, and if they had acted in the beginning, when the aggression was small there probably would have been no World War II.

If history has taught us anything, it is that aggression anywhere in the world is a threat to peace everywhere in the world. When that aggression is supported by the cruel and selfish rulers of a powerful nation who are bent on conquest, it becomes a clear and present danger to the security and independence of every free nation.

This is a lesson that most people in this country have learned thoroughly. This is the basic reason why we joined in creating the United Nations. And since the end of World War II we have been putting that lesson into practice we have been working with other free nations to check the aggressive designs of the Soviet Union before they can result in a third world war.

That is what we did in Greece, when that nation was threatened by the aggression of international communism.

The attack against Greece could have led to general war. But this country came to the aid of Greece. The United Nations supported Greek resistance. With our help, the determination and efforts of the Greek people defeated the attack on the spot.

Another big Communist threat to peace was the Berlin blockade. That too could have led to war. But again it was settled because free men would not back down in an emergency.

The aggression against Korea is the boldest and most dangerous move the Communists have yet made.

The attack on Korea was part of a greater plan for conquering all of Asia….

They want to control all Asia from the Kremlin….

The whole Communist imperialism is back of the attack on peace in the Far East. It was the Soviet Union that trained and equipped the North Koreans for aggression. The Chinese Communists massed 44 well-trained and well-equipped divisions on the Korean frontier. These were the troops they threw into battle when the North Korean Communists were beaten….

So far, by fighting a limited war in Korea, we have prevented aggression from succeeding and bringing on a general war. And the ability of the whole free world to resist Communist aggression has been greatly improved.

We have taught the enemy a lesson. He has found out that aggression is not cheap or easy. Moreover, men all over the world who want to remain free have been given new courage and new hope. They know now that the champions of freedom can stand up and fight and that they will stand up and fight.

Our resolute stand in Korea is helping the forces of freedom now fighting in Indochina and other countries in that part of the world. It has already slowed down the timetable of conquest….

But you may ask: Why can’t we take other steps to punish the aggressor? Why don’t we bomb Manchuria and China itself? Why don’t we assist Chinese Nationalist troops to land on the mainland of China?

If we were to do these things, we would be running a very grave risk of starting a general war. If that were to happen, we would have brought about the exact situation we are trying to prevent.

If we were to do these things, we would become entangled in a vast conflict on the continent of Asia and our task would become immeasurably more difficult all over the world.

What would suit the ambitions of the Kremlin better than for our military forces to be committed to a full-scale war with Red China?

It may well be that, in spite of our best efforts, the Communists may spread the war. But it would be wrong tragically wrong for us to take the initiative in extending the war.

The dangers are great. Make no mistake about it. Behind the North Koreans and Chinese Communists in the front lines stand additional millions of Chinese soldiers. And behind the Chinese stand the tanks, the planes, the submarines, the soldiers, and the scheming rulers of the Soviet Union.

Our aim is to avoid the spread of the conflict.

The course we have been following is the one best calculated to avoid an all-out war. It is the course consistent with our obligation to do all we can to maintain international peace and security. Our experience in Greece and Berlin shows that it is the most effective course of action we can follow.

First of all, it is clear that our efforts in Korea can blunt the will of the Chinese Communists to continue the struggle. The United Nations forces have put up a tremendous fight in Korea and have inflicted very heavy casualties on the enemy. Our forces are stronger now than they have been before. These are plain facts which may discourage the Chinese Communists from continuing their attack.

Second, the free world as a whole is growing in military strength every day. In the United States, in Western Europe, and throughout the world, free men are alert to the Soviet threat and are building their defenses. This may discourage the Communist rulers from continuing the war in Korea and from undertaking new acts of aggression elsewhere.

If the Communist authorities realize that they cannot defeat us in Korea, if they realize it would be foolhardy to widen the hostilities beyond Korea, then they may recognize the folly of continuing their aggression. A peaceful settlement may then be possible. The door is always open….

I believe that we must try to limit the war to Korea for these vital reasons: to make sure that the precious lives of our fighting men are not wasted; to see that the security of our country and the free world is not needlessly jeopardized; and to prevent a third world war.

A number of events have made it evident that General MacArthur did not agree with that policy. I have therefore considered it essential to relieve General MacArthur so that there would be no doubt or confusion as to the real purpose and aim of our policy.

It was with the deepest personal regret that I found myself compelled to take this action. General MacArthur is one of our greatest military commanders. But the cause of world peace is more important than any individual.
